P4 + 5o 2 p 4 o 10 , 1.5 moles of product was made in 30 seconds. what is the rate of reaction? 0.011 g/min 210 g/min 380 g/min 850 g/min

850.0 g/min.

Explanation:

The rate of the reaction = (ΔC/Δt) where,

ΔC is the change in concentration of reactants or products.

Δt is the change in time of the reaction proceeding.

The rate is needed to be calculated in (g/min).We need to calculate the amount of the product in (g) via using the relation (n = mass / molar mass).mass (g) = n x molar mass,n = 1.5 moles and molar mass of P₄O₁₀ = 283.88 g/mol.m = 1.5 x 283.88 = 425.82 g.ΔC = 425.82 g and Δt = 30 s / 60 = 0.5 min.The rate of the reaction = ΔC / Δt = (425.82 g / 0.5 min) = 851.64 g/min.

can be approximated to 850.0 g/min.

A1 a 2 a 3 ooh lol i think that's it

Answer : option a) 84explanation :

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
